f011a.w		*** stage - 1 ***

								  Game code
							[ F1 GrandPrix Star ]
---------------------------------------------------------------------------

Note: This game has some leftover code from Cisco Heat, it seems.

f9088.w		*** lap - 1 ***
fa008.w		($fa000 + $08) *** time (seconds) ***
fa2aa.l		($fa200 + $aa) speed << 16


---------------------------------------------------------------------------
							   Common Issues
---------------------------------------------------------------------------

- Some ROMs aren't used. I don't see big problems though.

- Screen control register (priorities, layers enabling etc.) - Where is it?

- In cischeat, at the start of some levels, you can see the empty scrolling
  layers as they are filled. In f1gpstar, I'm unsure whether they are
  correct in a few places: in the attract mode where the cars move
  horizontally, for example, the wheels don't follow for this reason, I
  think

- Sound communication not quite right: see Test Mode

---------------------------------------------------------------------------
								   To Do
---------------------------------------------------------------------------

- Use the Sprite Manager (when SPRITE_TYPE_UNPACK and SPRITE_TYPE_ZOOM
  will be usable together) for better looking rendering, better priority
  support and shadow sprites

- Use the Tilemap Manager for the road layers (when this kind of layers
  will be supported) for perfomance and better priority support.
  A line based zooming should be possible, for f1gpstar..

- Force feedback :)
